Spring.Net 简单实例-02(属性注入)

说明:接续Spring.Net 简单实例-01(IOC)

话不多说看操作

1:为UserInfo添加属性

2: 修改App.config中代码

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <spring>
    <context>
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net">
      <description>An  example that demonstrates simple IoC features.</description>
      <!--//type属性值必须是包含程序集名称在内的类型全名    "命名空间,程序集"-->
      <object name="UserInfoService"  type="YK.OA.SpringNet.UserInfoService, YK.OA.SpringNet">
        <!-- using setter injection... -->
        <!--//name代表属性名:UserName-->
        <property name="UserName" value="逍遥小天狼"/>
        </object>
    </objects>
  </spring>
</configuration>

App.config

3:进一步了解

添加一个Person类

4:同时修改UserInfoService类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace YK.OA.SpringNet
{
   public class UserInfoService:IUserInfoService
    {
       //1添加属性
       public string UserName { get; set; }
       //2再次添加一个属性
       public Person Person { set; get; }
        public string ShowMsg()
        {
            //此时没有给属性赋值,通过ioc容器实例化时赋值
            return "Hello World:" + UserName+",年龄: "+Person.Age;
        }
    }
}

UserInfoService

5:再次修改App.config文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <spring>
    <context>
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net">
      <description>An  example that demonstrates simple IoC features.</description>
      <!--//type属性值必须是包含程序集名称在内的类型全名    "命名空间,程序集"-->
      <object name="UserInfoService"  type="YK.OA.SpringNet.UserInfoService, YK.OA.SpringNet">
        <!-- using setter injection... -->
        <!--//name代表属性名:UserName-->
        <property name="UserName" value="逍遥小天狼"/>
        <!--通过ref对Person属性进行关联-->
        <!--name="表示UserInfo属性"  ref表示关联的object名称-->
        <property name="Person"  ref="Person"/>
      </object>
      <!--Person也是类,所以先object-->
      <object name="Person"  type="YK.OA.SpringNet.Person, YK.OA.SpringNet">
        <property name="Age" value="24"/>
      </object>
    </objects>
  </spring>
</configuration>

App.config

6运行结果

7:文件分离:当类文件过多后App.config文件过于臃肿

添加Xml文件实现代码分离,并将属性设置为"如果更新则复制"(很重要否则配置文件找不到xml文件)

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <description>An  example that demonstrates simple IoC features.</description>
  <!--//type属性值必须是包含程序集名称在内的类型全名    "命名空间,程序集"-->
  <object name="UserInfoService"  type="YK.OA.SpringNet.UserInfoService, YK.OA.SpringNet">
    <!-- using setter injection... -->
    <!--//name代表属性名:UserName-->
    <property name="UserName" value="逍遥小天狼"/>
    <!--通过ref对Person属性进行关联-->
    <!--name="表示UserInfo属性"  ref表示关联的object名称-->
    <property name="Person"  ref="Person"/>
  </object>
  <!--Person也是类,所以先object-->
  <object name="Person"  type="YK.OA.SpringNet.Person, YK.OA.SpringNet">
    <property name="Age" value="24"/>
  </object>
</objects>

services.xml

app.config可简化

一定 要在<context>到加入<resource uri="file://services.xml"/>

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <spring>
    <context>
      <resource uri="config://spring/objects"/>
      <!--//添加引用-->
      <resource uri="file://services.xml"/>
    </context>
    <objects xmlns="http://www.springframework.net">
      <!--<description>An  example that demonstrates simple IoC features.</description>
      --><!--//type属性值必须是包含程序集名称在内的类型全名    "命名空间,程序集"--><!--
      <object name="UserInfoService"  type="YK.OA.SpringNet.UserInfoService, YK.OA.SpringNet">
        --><!-- using setter injection... --><!--
        --><!--//name代表属性名:UserName--><!--
        <property name="UserName" value="逍遥小天狼"/>
        --><!--通过ref对Person属性进行关联--><!--
        --><!--name="表示UserInfo属性"  ref表示关联的object名称--><!--
        <property name="Person"  ref="Person"/>
      </object>
      --><!--Person也是类,所以先object--><!--
      <object name="Person"  type="YK.OA.SpringNet.Person, YK.OA.SpringNet">
        <property name="Age" value="24"/>
      </object>-->
    </objects>
  </spring>
</configuration>

App.config

运行 OK
